Abstract

1,139,917. Flocculating with polyacrylamide. NAUCHNO - ISSLEDOVATELSKY FIZIKO - KHIMICHESKY INSTITUT IM L. J. KARPOVA. 23 March, 1966, No. 12815/66. Heading C1C. [Also in Division C3] Water-soluble polyacrylamide with high molecular weights used as a flocculant, said polyacrylamide is prepared by polymerizing acrylamide by nuclear radiation or free radical initiator in an aqueous solution containing at least 20% by weight of acrylamide in the presence of an alkali metal hydroxide, an amino acid or salt thereof or an ammonium salt other than a free radical initiator or a mixture of these.
